Overview & Reviews

The General's brand-new HD truck lineup debuts with stronger frames; beefed-up suspensions, axles, brakes and cooling systems; new sheet metal; bigger interiors; and a trio of powerful new V8s -- a 6.6-liter Duramax turbodiesel and two gas engines, a hefty 8.1-liter and an improved 6.0-liter. One of the four transmissions, a new Allison five-speed automatic, is designed especially for towing and hauling with GM's helpful tow/haul mode and a new "grade-braking" feature.

• Most powerful engines you can buy, class-leading towing and payload.

• Generic styling, unproven build quality and service record.

  Great truck - 2001 GMC Sierra 3500
  By N.E. TM RPR - May 11 - 8:23 am

  Bought this truck end of July. Installed Una-Goose ball hitch in bed and drive it every day. I have 29,000 plus miles and have no reason to take it to dealer yet. I do all my own general service. I have towed loads as heavy as 16,000 without any problems. Trans handles all loads with ease with the grade braking. Only problem is keeping speed down,lots of power and I find myself going too fast.
